Apple M1 MacBook Air: 8GB RAM is plenty
I had a 64GB 12.9″ iPad Pro with Magic keyboard as my mobile workstation for over a year. Performance and battery life was great, no fan noise, and it ran almost every app I needed.

But the MacBook Air does all that and more, in a lighter and less costly package. Better performance. Two times the memory and 4x the storage. Dead quiet. Great battery life. Larger trackpad and display. Flexible multitasking and window layout. Excellent I/O options with Thunderbolt 3 and USB 4…
Apple charges an exorbitant $25/GB for RAM. However, the excellent performance of the 4GB iPad Pro gave me the confidence to buy the 8GB MacBook Air.
One day I wanted to see what it would take to overwhelm 8GB of RAM, so I left every app, window, and tab open all day. Safari and Firefox each with a dozen tabs open, Mail, Messages, Preview, Calendar, one or more Notes apps, Scrivener, and Final Cut Pro, and utilities including Copyclip, iStat Menus, Magnet, Default Folder, Typinator, Thesaurus, and a VPN.
After several hours of adding load I started seeing beach balls. I killed a few unused apps and all was good. I interpret this casual test to mean that for other than all-day, heads-down Pro users, 8GB of RAM is plenty. If you’re using the MacBook Air to make money, then splurge on 16GB. Everyone else, save your pennies.
